Nexgard for dogs is a prescription flea and tick medication that is used to treat pests on dogs. It should be given once a month, starting at 6 weeks old and continuing until 16 weeks of age. The dosage is dependent on your dog’s weight, with the maximum dose being 10mg per pound of body weight.
Nexgard is a chewable tablet that is given to dogs once a month in order to kill fleas. It also kills ticks and prevents heartworm disease. Nexgard’s active ingredient is afoxolaner, which is a type of insecticide that works by blocking an enzyme that is needed for fleas to live and multiply.
The active ingredient in Nexgard works by blocking the flea’s neural signals and causing paralysis. After ingestion, it begins to work within 30 minutes and can last up to 30 days in dogs. It will kill fleas quickly but may take a few months before all ticks are dead.
This medication comes in three different sizes: small dogs under 15 pounds, medium dogs between 15-30 pounds, and large dogs over 30 pounds.
The length of time it takes for Nexgard to kill fleas depends on how long it takes for the product to reach its full concentration in your dog’s bloodstream. This can take up to two weeks. Once the concentration reaches its peak, any fleas that bite your dog will die within 24 hours.
Nexgard’s manufacturer recommends treating your dog with a monthly dose of Nexgard if you have a high risk of getting bitten by ticks or live in an area where there are many ticks present.
How Nexgard Works?
Nexgard is a prescription flea and ticks medication for dogs. It works by using an ingredient called afoxolaner, which is a new active ingredient in the class of drugs known as isoxazoline. Afoxolaner blocks the transmission of nerve impulses in fleas, ticks, and other parasites.
It’s important to note that fleas have a nervous system that’s very similar to mammals, so when an afoxolaner blocks nerve impulses in insects, it also blocks them in mammals like cats and dogs. This is important because it means that when you use Nexgard on your dog, even if there might be some side effects for him or her (which we’ll talk about later), there won’t be any side effects for you or any other animals around your home.
The way Nexgard works its magic is by binding to receptors located on the surface of nerves in insects and parasites but not humans or other mammals. When this happens, it prevents the normal transmission of signals from one cell to another within their bodies, which results in paralysis and death within days.
Can My Dog Still Have Fleas After Using Nexgard?
Fleas are a common pest for dogs, and even though NexGard is an effective flea control medication, it’s not perfect.
It’s possible that your dog will still have fleas after using NexGard. However, this is rare. If your dog has fleas after using NexGard, it’s most likely because they were already carrying the parasite when you first administered the medication.
In order to prevent any possibility of a flea infestation in the future, we recommend that you continue to use NexGard every month as directed. This will ensure that your dog remains protected against all flea-borne illnesses such as heartworm disease and tapeworms.
Does Nexgard Kill Fleas or Make Them Jump Off?
Nexgard for Dogs is a monthly oral flea and tick treatment. It kills adult fleas and ticks, prevents infestations, and treats and controls tapeworms in dogs.
Nexgard is designed to work by releasing its active ingredient, afoxolaner, into your dog’s bloodstream to kill both fleas and the immature stages of brown dog ticks. In addition to killing adult fleas on contact, Nexgard may also kill flea larvae in the environment.
Fleas that are exposed to Nexgard may either die or jump off your dog’s body within 30 minutes of them consuming it. The exact number of fleas that will be killed depends on how many fleas are present at the time of administration the more fleas there are, the more likely some will survive long enough to reproduce again later.
How Long Does It Take for Nexgard to Start Working?
The answer to how long it takes for Nexgard to start working is that it depends on the size of your dog and its weight. You can expect to see results within about 24 hours, but if your dog is over 55 pounds or so, it may take a bit longer.
When you first give your dog Nexgard, it takes between 12 and 24 hours for the medication to reach its full efficacy level. However, this isn’t actually when you’ll see any changes in behavior, it’s just when the medication starts working at its optimal levels.
If your pup weighs under 20 pounds, it should start showing signs of improved behavior (less scratching) within 12 hours of taking its first dose of Nexgard. If they weigh between 20 and 50 pounds, they should start showing signs of improved behavior (less scratching) within 18 hours of taking their first dose of Nexgard. If they weigh more than 50 pounds, however, it may take up to 24 hours for them to start showing signs of improvement in their scratching symptoms.
Nexgard is a great option to consider if you’re looking for a fast-acting, effective flea treatment for your dog. The drug is easy to administer, and it can kill fleas on your pet within 30 minutes of administration. It’s safe to give your dog with existing health issues, and it’s even safe for puppies as young as six weeks old.
Nexgard will start working on the fleas within 30 minutes of administration, but it may take up to three days for all the fleas to be killed off. If you’re only treating one animal and don’t have any other pets in the house that could have brought new fleas into your home since the last time you treated it, then this won’t be an issue. But if you’ve been treating regularly with Nexgard or another monthly medication, then we recommend giving your dog a full three-day break between applications so that the new fleas aren’t killed off before they can reproduce enough eggs to repopulate your entire house again.
